RE: [TenTec] Orion Main- Sub-receiver differences

["Richard Detweiler" <rdetweil@hotmail.com>]

I'll confirm this on the Main RX.

I also have the 250Hz filters. With a similar station very near I could get 
up within 300Hz of his signal and still make the DX contact,  Fortunately we 
are both friends and we were and he knew I was playing with him,  His Mk V 
just couldn't handle the overload.  Only thing the Orion picked up from him 
was his clicks and that was not detremental.

The Orion's RX will be a standard for some time to come.
